低能离子对酪氨酸溶液损伤作用的光谱研究初报

利用气体我放电产生低能离子,其在放电间隙的电场加速下撞击水溶液样品。了低能离子作用后酪氨酸溶液的紫外及红外吸收光谱的变化。结果表明,气体放电产生的离子对Ｔｙｒ造成了多种损伤。不仅使化学键断裂,分子解体,而且外来的活性离子会与溶液中的元素形成新的化学基团,妆在受损伤分子碎片上组成新的损伤物质,充分体现了低能离子与物质相互作用的“离子沉积”效应。

Primary Study on Damage Effects of Low Energy Ions on Tyrosine Aqueous Solution

Low energy ions were produced in gas arc discharge, and the ions were accelerated into tyrosine (Tyr) aqueous solution. Changs in UV and infrared spectra of Tyr after this kind of ions' action were investigated. It was showed that the ions caused various damages on Tyr molecules. The ions not only destroyed the molecules, but also synthesize were new chemical groups with elements in the solution, then the new groups were inserted into the damage fragments to generate new substances. This is called "ions deposition" damage effects of low energy ions on substances.
